    Yep, now they are open but I wonder why the one on the lower passenger front isn't.

    I thought the same thing - although, nothing is said about functional vents in the video........weird.

    Front bumper vents definitely appear to be open now, but I really can't tell with any of the other ones. Will require closeups for sure. I am still a bit on the skeptical side about the side vent lol. The front fender/hood vent is definitely an easy one though, and should be reasonably functional for heat extraction judging from the design.

    Btw, little factoid (idk if I mentioned this before) but the fake fender vent on the FRS/BRZ was designed with this exact same idea in mind. When opened up it actually is an aerodynamically functional vent and actually does an okay job at heat extraction. I believe Velox/Verus ran some flow tests on it and found it to be effective. My BRZ has the vent opened up and it's great (although completely unnecessary on a non-boosted car), but I can absolutely see why you wouldn't want it on a production car. Water gets into the engine bay relatively easily, which while it isn't an issue, it makes it dirty af, which is annoying.

    just another form of suspension tuning.

    a wider rear tyre is chosen by manufacturers to tune a chassis towards understeer a little more than neutral/oversteer. it's generally safer in a high powered RWD car.

    A square setup is far more neutral

    Aren't these pictures from the stock GR Supra? I saw pics of a stock GR Supra showing the same thing, so the car does have brake cooling ducts, the front vent is just part of the lower front opening, rather than the teardrop vents below the headlights.

    Yes, that was from the stock version which is also covered on this GT4 concept. We know there is a duct in the production version so I wonder why the GT4 still has the rectangular cover. I thought it would have an inlet and piping. Or maybe the plate is a diffuser to channel the air to the L shaped vent below

    Do you have some more pics from Geneva? I mean what more Supras are there? Not only the GT4-Concept. I saw a red one on one pic. THX

    Huh, it's almost like the Chief Engineer wasn't bsing when he said the vents are fully functional, if one is ready to modify it.

    :rolleyes:

    I don't know why people thought he was BSing, a hole is a hole. Those blocked off vents means you dont have to cut a hole in the beauty side of your hood/door, design a vent for the hole, and repaint over factory paint to be functional, not that they would be pre-plumbed with only a $3 piece of plastic preventing functionality lol

    That's because the automotive industry has been faking the funk for too long, esp Toyota.

    Probably because that's where sensors are on the production car. I guess there is no "duct" where that is

    Which sensors are you referring to? Ambient temp? The parking sensors are on the vertical plane section of the grille.

    It's not symmetrical to the driver's side which has the tow hook cover so I'm wondering what's that blank section that's inside the rectangular piece on the passenger side.

    It's for the active safety stuff. I would assume there is a radar behind there in the production car.

    I just looked some more at the pictures. It would seem that 18x11 fronts are not pushing the limits. The fitment is still recessed into the fender quite a bit.
